Dust control device

Abstract

The invention relates to a dust retaining and filtering device which can be attached to a dust generating tool, for controlling the spread of dust and other particulate matter generated by grinding, sanding, polishing, burnishing and buffing devices. The device comprises a resilient skirt which curves outwardly along its bottom edge; a filter extending along the length of the skirt; means for mounting the filter along the length of the skirt and attachment means for securing the device to the dust generating tool.

The embodiments of the invention in which an exclusive privilege or property is claimed are defined as follows: 
     
       1. A device for trapping particulate matter generated during operation of a surface abrasion apparatus, comprising: a resilient wall member with a lower, surface engaging lip portion;   a filter adjacent said wall member;   retaining means comprising a plurality of hook and pile fasteners for securing said filter to said wall member;   attachment means for detachably securing said wall member to said surface abrasion apparatus.   
     
     
       2. An apparatus for retaining the dust generated by a tool selected from the group comprising grinding, sanding, polishing, burnishing and buffing devices; and adapted for use in combination with said devices, comprising a flexible skirt which curves outwardly along its bottom edge; a filter extending along the length of the skirt; means for mounting the filter along the length of the skirt and attachment means for securing the apparatus to the tool. 
     
     
       3. A device as claimed in claim 1 wherein said surface abrasion apparatus is a dust producing tool. 
     
     
       4. A device as claimed in claim 1 wherein said surface abrasion apparatus is a floor sanding apparatus. 
     
     
       5. A device as claimed in claim 4 wherein said dust producing tool is a floor polishing apparatus. 
     
     
       6. A device as claimed in claim 4 wherein said dust producing tool is a floor burnishing apparatus. 
     
     
       7. A device as claimed in claim 4 wherein said dust producing tool is a floor buffing machine. 
     
     
       8. A device as claimed in claim 1 wherein said filter is of sponge-like material. 
     
     
       9. A device as claimed in claim 8 wherein said filter comprises reticulated polyurethane foam.
